U.S.A.

 The median price last year for all newly constructed houses in the United States was $176,700, far beyond the reach of low-income families. With an average cost in the United States of $48,537--and an average no-interest monthly mortgage payment of $266.

	Certain measures are in place to reduce the potential for termite attack. For example, according to code, wood cannot be within six inches from the ground, or if it is, it must be rot- and insect-resistant wood. Habitat house foundations also should have a 5 percent grade slope to ensure that water doesn't enter.
	A structurally sound roof with adequate flashing eliminates the risk of water problems. In the United States, 90 percent of Habitat houses have asphalt shingles, and the ceilings are insulated to prevent heat loss and/or gain.
	Strong walls, with sound siding, windows and flashing, prevent moisture from setting in.
	New plumbing saves floors from leaking water and eventual rotting.
	Subfloor insulation keeps heat from escaping, resulting in a more efficiently heated house.
